What type of ignition coil should I buy ?? resister type or normal it is a1979 1600cc


1979 1600cc what? Early chevy cars (1963 for example) had a resistor wire between the coil and the ignition switch that took the place of a resistor coil. The theory here is that when cranking to start, you want the full 12 volts that by ohms law means you have lower amps, but higher voltage to jump the cold spark plug gap and make for easier starting. Once running, you have a resistor that reduces voltage but increases amps, to get a fuller burn and better efficiency. THEREFORE, you can test for voltage being supplied to the coil at "key on" to see which coil you need. If you have full 12 volts, buy resistor coil. If more like 6.8 or so, use non resistor coil.

What kind of amp can adequately power P112 S8 subs


you shouldnt run it at 8 ohm it shows what ohms it can handle . to run it at 1 ohm you would need 2 subs to do this. and no i wouldnt run an 8 ohm sub on the amp.

Hellow, I own a rx-v2090 , everythings works, the problem is if i crank the volume to 11 to 12 O' clock position, it looses the base and half a minute later it shut itself. please can you explain to me...


Sounds like from what you describe is that your speakers ohms might be to low for the Receiver and making it over heat.Take a look at your speakers ohms rating and then look at what your Receiver is rated for most receivers can handle down to about 6 ohms nothing lower.There are some out there that can handle lower but from what I can see about yours it handles about 8 ohms.

How do I drop olhs


To drop the ohms you wire in parallel. If your sub has dual 4 ohm coils you would connect both positives from the coils together as well as join the negatives together- this will give you 1 set of positive and negative wires-this + and - is now a 2 ohm load do the same to your other sub and you have a pair of 2 ohm subs. Wire the positives together from both subs as well as the negatives again and you now have a 1 ohm load. If you have dual 2 ohm coils you can get as low as 1/2 ohm of resistance.As far as i know the jl 500 puts the same amount of power into 1.5 through 4 ohms as long as you stay in that range your amp will be fine

My subwoofer is cutting off. I replaced to fuse on the main power, and it works when I have the source on a very low volume level but when I turn the volume up, it cuts off. I have 1 alpine type R12 and a...


You are probably running the ohms too low for the amp and its drawing too much current. Consult your amp manual for proper load level capacity and you can wire it accordingly. More then likely its only 4ohm stable bridged and your running it at 2 or less depending on if your subs have single or dual voice coils. Try connecting one pos speaker terminal to the other speaker neg then run the left ofer pos on one speaker and the the left over neg directly to the amp (series) I will raise the ohms (amp makes less power) but should not cut off unless the subs ohm are still to low, if this is the case you need a sub with a higher ohm rating or an amp wiht a lower rating...

I have 2 12 in kicker cvr tryna drop to lower ohm


http://www.colomar.com/Shavano/dvc_spkr_wiring.html

Use the above site for several wiring schematics on dual voice coil speaker hookups. It will show how to wire for different impedance.
Also, I think the CVR 12's come in 2 ohm and 4 ohm impedance. See if you can check yours to determine which you have....

I need to know how to wire my 2 12' kenwood w3514 dvc sub woofers parellel


For parallel connections, simply wire posotive to positive and negative to negative. But beware! this lowers the impedence (ohms) by half. In other words if you have 4 ohm woofers, in parallel they would be two ohms. Make sure your amp can handle that. Otherwise connect them in series.

Coolant Temp sensor


The coolant temperature sensor should read at approx 1,800 ohms between 68 and 88 degrees F. As the temperature lowers, the resistance rises. More ohms. As the temperature rises, the resistance lowers. Less ohms. At 210 degrees, the ohms would be about .15 K ohms.

The 89 and the 12 figures are wrong.

You've pretty much hit the nail on the head. Two 2 ohm subs in parallel would give you 1 ohm, and two 2 ohm subs in series would give you 4 ohms. 1 ohm would be overloading the amp but 4 ohms is slightly "underloading" the amp.

Your best solution with the gear you have (i.e. not buying new subs or a new amp) is to put the subs in series (4 ohms). True, you'll be putting about 200W into each sub, but according to page 4 of the owner's manual for the subs, 200W is just a tad under the optimum level recommended for the sub anyway.

Amp goes into protection


First change the wire,and disconnect the subwoofers to check if the amplifier turn on without going in to protection mode,if the amplifier go to protection mode you gotta change the Audio amplifiers IC's because they are in short circuit.And if don't go in to protection put one speaker at a time to check if one of them are damaged.Good luck.
